- The Polycraft FC3680 being used in two silicone moulds made from T20 silicone. The FC3680 is a fast cure polyurethane resin suitable for a wide range of casting and rapid prototyping projects.
I'm trying to use this stuff currently, emphasise on trying, because so far all my attempts have resulted in bubbles and I'm genuinely losing motivation due to the frustration. I have tried dribbling the resin in slowly to avoid the bubbles but the short pot life means I end up wasting alot.
Hi, if bubbles are causing issues, there are a couple options, 1: the expensive option of casting under pressure using a pressure chamber (including compressor) or you could try using a soft bristle brush to quickly brush the resin over the face of the casting / or gently roll the resin over the surface and pop any small bubbles you see, you can allow the resin to reach an early stage of gel and fill up, or if you have time pour the rest of the resin in and fill the mould up that way. In reference to bubbles also, if the material is colder than specified it will be higher in viscosity so you'll tend to trap more air mixing also, warming it up will help but this will also affect potlife so its a balancing act. If you want further guidance pop us an email or give us a call, you can find our telephone number and email address on the website (or on the labels of the containers).
well done . I can't find that T 20? Can I use the dye from resin to silicone
T20 link www.mbfg.co.uk/polycraft-t-20.html - the dyes cannot be interchanged unfortunately
Do you need to use a respirator with this resin? Is it safe to use at home?
We provide the safety datasheets on the website which can be viewed before and after purchase, we highly recommend reading before using the materials. Ultimately the decision to wear a mask or not is your responsibility.

High click-through rate according to analytics, the videos are primarily visual insights for potential customers. This particular video isn't a tutorial so it only really benefit those who are considering the material and want to see how the material pours / what its like to use etc.
Does this resin have any flex as a final product?
It would have very little flex especially if cast at any depth, it cures to quite a rigid Shore D75
I love the resin and the products, but I'm not impressed with the final pouring. Far too many air bubble leaving pock marks and holes in the part.
Try it again. Only this time, take a small paintbrush and brush resin into the crevices of the raised letters beore you pour it in. That will drive the air out and give you a better final product.
Hi, brushing the surface can help to pop surface bubbles, otherwise you might wish to look at a release agent if surface tension is an issue.
@@MBFibreglass, I have over 10 years of experience with various types of resins. Your idea of release agent is good, but a simple paintbrush is best for preventing small airbubbles getting trapped in highly detailed areas.
@@Alan_AB Thanks for the tips Alan.
